-      TODO: <a href="https://golang.org/cl/295371">https://golang.org/cl/295371</a>: do not overflow key memory in GetQueuedCompletionStatus

+      <a href="/pkg/syscall/#PostQueuedCompletionStatus"><code>PostQueuedCompletionStatus</code></a>
+      functions are now deprecated. These functions have incorrect signatures and are superseded by

-      TODO: <a href="https://golang.org/cl/313653">https://golang.org/cl/313653</a>: restore signal mask after setting foreground process group
+      On Unix-like systems, the process group of a child process is now set with signals blocked.
+      This avoids sending a <code>SIGTTOU</code> to the child when the parent is in a background process group.
